Abstract
The present invention involves a skate that can be converted from an in-line wheel configuration in which all of the skate wheels are coplanar to a parallel or quad wheel configuration, and vice versa. The skate includes a foot or shoe enclosure (4), a wheel chassis (10), a wheel support (52), at least two wheels (50), and mechanisms which position the wheel chassis at a center point and allows the wheel chassis to pivot the wheels from an in-line to a parallel configuration. The positioning mechanisms include tie rods (18), yokes (84, 86), gear sets (106), and externally mounted rods or panels (116). A post (30) on the bottom of the enclosure may include a threaded portion which is engaged by a nut (36) to rotationally secure the position of the wheel chassis, or the post may include a portion (94) of enlarged diameter supporting a spring (104) which biases the wheel chassis into the post. A brake (122) is provided to allow the user to slow or stop the skate in a controlled manner.
Claims
1. A skate comprising: an enclosure (4) ; a base frame (6) attached to said enclosure; at least one vertical post (30) attached to said base frame; at least one chassis (10) , each said wheel chassis having a body pivotally attached to said vertical post, a pair of wheels (50) ; a pair of wheel supports (52) for rotatably supporting said wheels in vertical rotational planes relative to a ground surface, each said wheel support being pivotally connected to a respective end of said wheel chassis for movement about a vertical axis; one of said enclosure, said base frame, and said post being a fixed member; characterized in that said wheel chassis further includes means (18, 30, 52; 106, 30, 52; 84, 88, 92, 30, 52; 86, 90, 30, 52; 116, 30, 52) for connecting said wheel supports to the fixed member, said connecting means changing the pivotal position of the vertical axes of said wheel supports in response to pivotal movement of said wheel chassis relative to said fixed member, whereby the vertical rotational planes of said pairs of wheels may be selectively arranged either in-line along a longitudinal axis of the skate or transversely along each side of the longitudinal axis in response to a selected pivotal position of said wheel chassis.
2. The skate of Claim 1 characterized in that said post includes a threaded portion, and said skate further comprising a fastener (36; 100) threadably engaging said threaded portion to rotationally secure the position of said wheel chassis.
3. The skate of Claim 1 characterized in that said post includes a portion (94) of enlarged diameter supporting a biasing means (104) which biases said wheel chassis into said post.
4. The skate of Claim 1 characterized in that said connecting means includes two tie rods (18) , each tie rod connecting the fixed member and one of said wheels, said tie rods have a predetermined length which maintains the angular position of said wheels relative to the fixed member regardless of the angular position of said wheel chassis.
5. The skate of Claim 1 characterized in that said connecting means includes gears (106) disposed within said wheel chassis and connecting the fixed member and one of said wheels.
6. The skate of Claim 1 characterized by a yoke (84; 86) operably connecting the fixed member and one of said wheels, and biasing means (88, 90; 92) for urging engagement of said yoke with the fixed member and said wheels so that by deactivation of said biasing means, said yoke allows independent positioning of said wheels.
7. The skate of Claim 1 characterized by a second chassis supporting a second pair of wheels, said connecting means includes an elongate member (116) disposed externally of said chassis and said second chassis, said elongate member connecting one of said wheels of said wheel chassis with one of said wheels of said second wheel chassis so that the rotation of said wheel chassis and said second wheel chassis is synchronized.
8. The skate of Claim 1 characterized by means (72, 73; 74, 75; 76, 78; 80, 34') for aligning said chassis relative to the fixed member.
9. The skate of Claim 1 characterized by brake means (122) attached to one of said wheels for slowing said skate.
10. The skate of Claim 8 characterized in that said aligning means includes a plurality of discrete aligned positions for said wheel chassis relative to the fixed member.
11. The skate of Claim 9 characterized by a plurality of wheel supports (52) , each said wheel support including a U-shaped crosspiece (54, 56) journalling an axle (58) which rotatably supports each of said wheels, said brake means being mounted on one of said wheel supports.
12. The skate of Claim 11 characterized in that said brake means includes a cantilevered arm (124) pivotally attached to said one of said wheel supports adjacent said one of said wheels, said cantilevered arm having one end with a friction surface (128) disposed adjacent to said wheel.
13. The skate of Claim 12 characterized by a roller (126) rotatably mounted on the other end of said cantilevered arm.
14. The skate of Claim 1 characterized in that said connecting means provides for synchronized orientation of said wheels, and said wheels are maintained in an angular position corresponding to the longitudinal direction of said enclosure throughout the rotation of said wheel chassis.
15. The skate of Claim 5 characterized by a belt (114) operably connecting said gears.
16. The skate of Claim 4 characterized in that said enclosure includes a collar (70) fixed to the fixed member and engaging said tie rods, and said tie rods are pivotally connected to said at least two wheels.
17. The skate of Claim 4 characterized by two inserts (12) rotatably disposed in said wheel chassis and fixed to a respective one of said at least two wheels, said tie rods being pivotally connected to a respective one of said inserts.
